Medical devices utilizing animal tissues and their derivatives — Part 1: Application of risk managem...
This document applies to medical devices other than in vitro diagnostic medical devices manufactured utilizing materials of animal origin, which are non-viable or have been rendered non-viable. It specifies, in conjunction with ISO 14971, a procedure to identify the hazards and hazardous situations associated with such devices, to estimate and evaluate the resulting risks, to control these risks…
Determination of the characteristic limits (decision threshold, detection limit and limits of the co...
This document specifies a procedure, in the field of ionizing radiation metrology, for the calculation of the "decision threshold", the "detection limit" and the "limits of the coverage interval" for a non‑negative ionizing radiation measurand when counting measurements with preselection of time or counts are carried out. The measurand results from a gross count rate…
Implants for surgery — General guidelines and requirements for assessment of absorbable metallic imp...
This document established the currently recognized approaches and special considerations needed when evaluating the in vitro and in vivo performance of absorbable metals and implants fabricated, in whole or in part, from them. This document describes how the evaluation of these metals can differ from those utilized for permanent non-absorbable implantable implants (or subcomponents), in that…
